12 | 13 | # History 14 | 15 | 2020-01-12 Updated to .NET Core 3.1, NLog.Web.AspNetCore 4.9.0 16 | 17 | 2018-04-04 Updated to .NET Core 2.0, NLog 4.5.1, and Elasticsearch Nuget package 18 | 19 | 20 | ## ASP.NET Core logging with NLog and MS SQLServer 21 | 22 | This article shows how to setup logging in an ASP.NET Core application which logs to a Microsoft SQL Server using NLog. 23 | 24 | The NLog.Web.AspNetCore Nuget package is added to the dependencies in the csproj file. 25 | 26 | ```xml 27 | 28 | 29 | 30 | netcoreapp3.1 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | PreserveNewest 48 | 49 | 50 | 51 | ``` 52 | 53 | 54 | Now a nlog.config file is created and added to the project. This file contains the configuration for NLog. In the file, the targets for the logs are defined as well as the rules. An internal log file is also defined, so that if something is wrong with the logging configuration, you can find out why. The ${gdc:item=configDir} is set in the application code. 55 | 56 | ```xml 57 | 58 | 63 | 64 | 65 | 66 | 68 | 69 | 71 | 72 | 73 | 74 | 75 | 76 | ${gdc:item=connectionString} 77 | 102 | 103 | 104 | insert into dbo.Log ( 105 | Application, Logged, Level, Message, 106 | Logger, CallSite, Exception 107 | ) values ( 108 | @Application, @Logged, @Level, @Message, 109 | @Logger, @Callsite, @Exception 110 | ); 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | 131 | 132 | 133 | 134 | 135 | 136 | ``` 137 | 138 | 139 | Now the database can be setup. You can create a new database, or use and existing one and add the dbo.Log table to it using the script below. 140 | 141 | ```sql 142 | SET ANSI_NULLS ON 143 | SET QUOTED_IDENTIFIER ON 144 | CREATE TABLE [dbo].[Log] ( 145 | [Id] [int] IDENTITY(1,1) NOT NULL, 146 | [Application] [nvarchar](50) NOT NULL, 147 | [Logged] [datetime] NOT NULL, 148 | [Level] [nvarchar](50) NOT NULL, 149 | [Message] [nvarchar](max) NOT NULL, 150 | [Logger] [nvarchar](250) NULL, 151 | [Callsite] [nvarchar](max) NULL, 152 | [Exception] [nvarchar](max) NULL, 153 | CONSTRAINT [PK_dbo.Log] PRIMARY KEY CLUSTERED ([Id] ASC) 154 | WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] 155 | ) ON [PRIMARY] 156 | 157 | ``` 158 | 159 | The table in the database must match the configuration defined in the nlog.config file. The database target defines the connection string, the command used to add a log and also the parameters required. 160 | 161 | You can change this as required. As yet, most of the NLog parameters, do not work with ASP.NET Core, but this will certainly change as it is in early development. The NLog.Web Nuget package, when completed will contain the ASP.NET Core parameters. 162 | 163 | 164 | Now NLog can be added to the application in the Startup class in the configure method. The AddNLog extension method is used and the logging directory can be defined. 165 | 166 | ```csharp 167 | public void Configure(IApplicationBuilder app, IWebHostEnvironment env) 168 | { 169 | GlobalDiagnosticsContext.Set("configDir", "C:\\git\\damienbod\\AspNetCoreNlog\\Logs"); 170 | GlobalDiagnosticsContext.Set("connectionString", Configuration.GetConnectionString("DefaultConnection")); 171 | 172 | if (env.IsDevelopment()) 173 | { 174 | app.UseDeveloperExceptionPage(); 175 | } 176 | else 177 | { 178 | app.UseExceptionHandler("/Home/Error"); 179 | } 180 | 181 | 182 | app.UseDefaultFiles(); 183 | app.UseStaticFiles(); 184 | 185 | app.UseRouting(); 186 | 187 | app.UseEndpoints(endpoints => 188 | { 189 | endpoints.MapControllerRoute( 190 | name: "default", 191 | pattern: "{controller=Home}/{action=Index}/{id?}"); 192 | }); 193 | } 194 | 195 | ``` 196 | 197 | ```csharp 198 | using System; 199 | using System.Collections.Generic; 200 | using System.Linq; 201 | using System.Threading.Tasks; 202 | using Microsoft.AspNetCore.Hosting; 203 | using Microsoft.Extensions.Configuration; 204 | using Microsoft.Extensions.Hosting; 205 | using Microsoft.Extensions.Logging; 206 | using NLog; 207 | using NLog.Web; 208 | 209 | namespace AspNetCoreNlog 210 | { 211 | public static class Program 212 | { 213 | public static void Main(string[] args) 214 | { 215 | var logger = NLog.Web.NLogBuilder.ConfigureNLog("nlog.config").GetCurrentClassLogger(); 216 | try 217 | { 218 | logger.Debug("init main"); 219 | CreateHostBuilder(args).Build().Run(); 220 | } 221 | catch (Exception exception) 222 | { 223 | //NLog: catch setup errors 224 | logger.Error(exception, "Stopped program because of exception"); 225 | throw; 226 | } 227 | finally 228 | { 229 | // Ensure to flush and stop internal timers/threads before application-exit (Avoid segmentation fault on Linux) 230 | NLog.LogManager.Shutdown(); 231 | } 232 | } 233 | 234 | public static IHostBuilder CreateHostBuilder(string[] args) => 235 | Host.CreateDefaultBuilder(args) 236 | .ConfigureWebHostDefaults(webBuilder => 237 | { 238 | webBuilder.UseStartup(); 239 | }) 240 | .ConfigureLogging(logging => 241 | { 242 | logging.ClearProviders(); 243 | logging.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace); 244 | }) 245 | .UseNLog(); // NLog: Setup NLog for Dependency injection 246 | } 247 | } 248 | 249 | ``` 250 | 251 | Now the logging can be used, using the default logging framework from ASP.NET Core. 252 | 253 | An example of an ActionFilter 254 | 255 | ```csharp 256 | using Microsoft.AspNetCore.Mvc.Filters; 257 | using Microsoft.Extensions.Logging; 258 | 259 | namespace AspNetCoreNlog 260 | { 261 | public class LogFilter : ActionFilterAttribute 262 | { 263 | private readonly ILogger _logger; 264 | 265 | public LogFilter(ILoggerFactory loggerFactory) 266 | { 267 | _logger = loggerFactory.CreateLogger("LogFilter"); 268 | } 269 | 270 | public override void OnActionExecuting(ActionExecutingContext context) 271 | { 272 | _logger.LogInformation("OnActionExecuting"); 273 | base.OnActionExecuting(context); 274 | } 275 | 276 | public override void OnActionExecuted(ActionExecutedContext context) 277 | { 278 | _logger.LogInformation("OnActionExecuted"); 279 | base.OnActionExecuted(context); 280 | } 281 | 282 | public override void OnResultExecuting(ResultExecutingContext context) 283 | { 284 | _logger.LogInformation("OnResultExecuting"); 285 | base.OnResultExecuting(context); 286 | } 287 | 288 | public override void OnResultExecuted(ResultExecutedContext context) 289 | { 290 | _logger.LogInformation("OnResultExecuted"); 291 | base.OnResultExecuted(context); 292 | } 293 | } 294 | } 295 | 296 | 297 | ``` 298 | 299 | The action filter is added in the Startup ConfigureServices services. 300 | 301 | ```csharp 302 | public void ConfigureServices(IServiceCollection services) 303 | { 304 | services.AddSingleton(); 305 | // Add framework services. 306 | services.AddControllers(); 307 | 308 | services.AddScoped(); 309 | } 310 | 311 | ``` 312 | 313 | And some logging can be added to a MVC controller. 314 | 315 | ```csharp 316 | using System; 317 | using System.Collections.Generic; 318 | using Microsoft.AspNetCore.Mvc; 319 | using Microsoft.Extensions.Logging; 320 | 321 | namespace AspNetCoreNlog.Controllers 322 | { 323 | [ServiceFilter(typeof(LogFilter))] 324 | [Route("api/[controller]")] 325 | public class ValuesController : Controller 326 | { 327 | private ILogger _logger; 328 | 329 | public ValuesController(ILogger logger) 330 | { 331 | _logger = logger; 332 | } 333 | 334 | [HttpGet] 335 | public IEnumerable Get() 336 | { 337 | _logger.LogCritical("nlog is working from a controller");
